i hold it essential for a teacher to be both intellectually and morally honest. this does not mean being a plaster saint. it means that he will be aware of his intellectual strengths, and limitations, and will have thought about and decided upon the moral principles by which his life shall be a bit of an actor. that is part of the technique of teaching, which demands that every nor and then a teacher should be able to put on an act - to enliven a lesso, correct a fault , or award praise.
